k TROLLEY-WIRE SUPPORT.

To all whom it may concern Be it known that we, GIBsON H. (tors and LEE RoLLrNs, citizens of the United States, residing at Roda, in the county of Vise and State of Virginia, have invented certain new and useful Improvements in Trolley Wire Supports; and we do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in trolley wire supports, and has for its principal object to provide a device which will easily and quickly clamp a trolley wire and hold the same firmly in )lace.

I Another object of the invention is to provide a trolley wire support which is so constructed as to avoid engagement with the trolley wheel when the same is passing over the support.

A further object of the invention is to provide a novel means for tightening the sup- 5 port on the wire to prevent the wire from slipping from place.

Still another object of the invention is to provide a device which will prevent the wire from twisting or from becoming loosened on curves.

A still further object of the invention is to provide a novel means for tightening the clamp so that the wire may be firmly held in place and tightened from time to time. I at \Vith these and other objects in View, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which,

Figure 1 is a view partly in section of a trolley wire support constructed in accordance with this invention,-Fig. 2 is a sectional view taken at right angles to Fig. 1,Fig. 3 is a detail perspective view of the adjusting colas lar, Fig. 4 is a plan view of the wedge, and

Fig. 5 is a fragmentary perspective view of the wrench used in connection with this device.

Referring to the drawings by characters to of reference, the numeral 1 designates the main supporting body which is provided near its upper end with suitable screw threads 2. A central threaded axial bore 3 is formed in the supporting body 1 and this body is bifurcated at its lower end to form Patented May 23, 191%. Serial No. 15,011.

a pair of downwardly extending projections 4 having formed thereon the ears 5. These ears are provided with suitable apertures for the reception of the pivot pins 6 by which the aw members designated generally a by the numeral 7, are pivotally held in place. The aw members, hereinbefore referred to, comprise the jaws 8 and the operating levers 9, intermediate which are suitable offset portions, through which the pivot pins 6 extend. The levers 9 are provided at their upper ends with the cam faces 10, in connectlon with which the wedge member, illustrated in Fig. 4 cooperates.

The wedge member hereinbefore referred to to, is designated generally by the numeral 11. and comprises the body 12 which is formed with a central opening 13 and is provided at each end with the can faces 14, which cooperate with the cam faces 10 of N the levers 9 in clamping the' trolley wire. A suitable groove 15 is formed in the body 12 and is arranged to receive the pin 16 carried by the bodyl so that the wedge membzlar will be prevented from turning when in to p ace.

Cooperating with the screw threaded portlon 2 of the supporting member 1 is the adjuster designated generally by the numeral 17, which comprises the body 18 having formed thereon the flanges 19 and 20, each of which is provided with the diamet rically opposed notches 21 which are arranged in alinement to receive the lugs 'on the wrench which will be more fully here- W inafter described. The body 18 is formed with a centrally screw threaded aperture 22 which receives the threaded end 2 of the supporting member 1. It will thus be seen that as the adjuster is screwed down against the t5 wedge member 11 the jaws 8 of the jaw members 7 will be more firmly forced toward each other and a tighter grip on the trolley wire will be taken.

In order to move the adjusting screw the mo wrench, best illustrated in Fig. 5, is provided which comprises the handle 23 having formed at one end the head designated generally by the numeral 24. This head comprises the arm 25 which is relatively long 1M and outwardly curved at its end as at 26, and the arm 27 which is relatively short and provided near its end with the lugs 28 which are disposed on opposite sides. These lugs 28 are arranged to engage in the notches 21,

' while the arm 2 of the wrench head lies between the flanges 19 and 20. It will thus verse motion is given and it will be evident thatthelugs 28 will ride out of their respective notches and be pushed around until they engage in the adjacent notches, and

- uponreversing the movement it will'be evi dent that a fresh grip will be taken. t

From the foregoing it will be evident that j a particularly simple and efficient clamp for the trolley wire is'provided which will effectivel-y grip the wire and hold the same case the wire should become lo0sened,'may' againstaccidental movement and which, in

be easily and quicklytightened,

While the foregoing there has been shown and] described the preferred embodi- 1 ment-of this invention,"it is to be understood j that such changes maybe made in; the com-' bination'andarrangement of parts as will fa ll within the spirit and scope-ofthe inven tion as claimed,

'What is claimed-is:

1. VA-trolley wire support of the class described comprising arbody member being exteriorly screw threaded and provided at its upper end with an interior bore, the

lower end of said body member being bifurdated forminga pair of arms, said arms having, apertures therethrough, a stop lug formed on said body, a wedge slidably mounted on said body provided with a vertical groove in itsinner wall adapted to engage the stop lugformed on the body to prevent the rotation of the same,,.a pair'of" jaws pivoted on opposite sides of saidgbody and between the arms, the upper ends of saidjaws engaging the outer surfaces of the wedge forcing the same outwardly and ga t heir inner end toward one another for firmly gripping a wire therebetween and means for engaging the exterior threads of the body and the wedge to prevent upward movement of the same. b

I 2. A trolley wire support of the class described comprisinga bodyfsaid body provided with exterior screw threads at its upper end, a bore formed in the upper end of I said body, the lower end of said body being bifurcated'forming a pair of arms, said armsprovlded with apertures in opposite corners, a stop lug formed centrally in one wall of said'body and projecting outwardly therefrom, a pair of jaws, said jaws comprising alever portion and a clamping portion formed on one end of the lever portion, a projection formed centrally on said lever portion, said projection provided with apertures to aline with the apertures of the ears formed on the arms, and means for piyotally holding the projections of the jaws between the arms, a wedge provided with cam fa des slidably mounted on said body, said wedge provided with an interior vertical groove, said groove adaptedto engage the lug on the body when positioned thereupon to prevent rotation of the same, and a circular adjusting member provided with interiorscrew threads adapted to engage the exterior screw threads of the body and force the wedge members down between the-levers for forcing the same outwardly and their clamping ends inwardly for supporting a wire therebetween and hold the wedge against upward movement.

3. A wire support of the class described comprising a circular body having a bore formed in its upper .end, said circular body being screw threaded exteriorly and interiorly, a stoplug formed centrally on one wall of said body and projecting outwardly therefrom, the lower-end of, said body being bifurcated forming a pa'ir of substantially rectangular arms, levers pivotally connected .between the arms, said levers provided at their lower ends with clamping members, a

vwedge, said wedge provided with a groove adapted to slidably engage the body, said groove engaging the stop lug for preventing the rotation of the same upon the body, the outer faces of said wedge engaging the inner faces of the levers forcing the same outwardly, an adjuster, said adjuster comprising a body, angular flanges formed on opposite ends of said body, said flanges rov ded with a plurality of opposed notc ies, said second mentioned body provided with interior screw threads, being screw threaded down over the screw threads of the first mentioned body to prevent the upward movement of the wedge member.

In testimony whereof we aflix our signatures in presence of two witnesses.
